[44net] network summary software?

I am looking for something like webalizer, but more encompassing. It has to run on a webserver. It should show a summary of various different types of network traffic. Things that come to mind that are close to what I am looking for: http://awstats.sourceforge.net/ http://oss.oetiker.ch/mrtg/ http://humdi.net/vnstat/ Something that analyzes the packets passing through and keeps statistics; ie. -most active IP addresses on the network in terms of traffic -stats on the types of traffic, www, ftp, etc/ Something that can provide insight into what applications and services are being used on the network. Does anything come to mind that fits this description?
